Allegro Sigrity PI provides advanced signoff-level accuracy
for AC and DC power-integrity PI analysis both during and post-layout. The solution comprises a number of Sigrity tools including.
Sigrity PowerSI for AC analysis tool that also supports S-parameter model extraction of coupled signal, power, ground, and design-stage EMI analysis using the hybrid solver extraction engine.
Sigrity PowerDC for DC analysis tool to provide thermal-aware IR drop analysis
Sigrity OptimizePI, for decoupling capacitor optimization to optimizes your design’s decoupling capacitor scheme to maximize performance while minimizing cost.
Sigrity PowerSI 3D EM Extraction Option (3DEM) for three-dimensional (3D) full-wave and quasi-static electromagnetic (EM) field solver provides S-parameter model extraction using model reduction technology. For accuracy with complex 3D structures, the tool features adaptive finite element mesh (FEM) refinement technology.
